1 General Description

1.1 Introduction

This chapter describes the purpose, principle of operation and user controls of the Hinet series on-line Uninterruptible
Power Supply (UPS).
The Hinet series UPS is connected between a critical load, such as a computer, and the mains. Its purpose is to provide
the load with regulated power under all rated load and input supply conditions; i.e. the power provided by the UPS will
be protected from any voltage or frequency variations on the input power supply, or variations in the supply due to
electrical noise, and will continue during periods of input power supply failure. A battery provides a standby power
source for the UPS when the input power supply fails.

1.2 Equipment construction

The equipment is constructed around a steel frame with removable panels. The door can be open to give easy access to
the input, bypass, output, reserve line circuit breakers and battery C.B. fused switch, while protecting them from
accidental operation.
An LCD control panel on the front of the cabinet permits the operator to monitor the UPS.
The cabinet houses both the power components and the batteries.
It is carried on four wheels. Jacking feet help to support the UPS, and also prevent it from moving once it has been
wheeled into its final position. These feet are also used to secure the equipment to its shipping pallet during transit.

Cooling is by internal fan. Air is drawn in from beneath the UPS and exhausted through ventilation grills of the front
panel. These areas must be kept free of anything that may avoid the air flow into and out of the unit.

1.2.1 Principle of operation
Normal operation

During normal operation, i.e. when the UPS input supply is present and within specification, both the converter and
inverter sections are active and the automatic by-pass is turned on to connect the inverter output to the critical load
terminals. The battery fuse-holder switch is also closed and the battery is therefore permanently float charged at the d.c.
terminals voltage level.

Mains Failure

If the mains has a failure or is out of tolerance the converter will be supplied from the battery, while the inverter will
continue to operate for a period of time which depends on the load and the capacity of the battery. If the mains supply
has not returned within this time, the inverter will go off automatically and an alarm condition will appear on the UPS
operator control panel.
Critical load will not be interrupted in the event of a drop or return of the AC power mains.

Return of power mains

When the mains returns within the required tolerance, the converter will be automatically supplied from mains,
supplying power to the inverter and recharging the battery at the same time. There will be no interruption of the critical
load.

UPS fault

In the event of an inverter failure, the automatic by-pass will automatically transfer the load onto the mains with no
interruption. In such an event, request qualified technical assistance.
The load will be transferred with no interruption if the inverter is synchronised with the mains; if this is not the case,
there will be an interruption of some milliseconds.
The intervention of the automatic by-pass line is shown on the front panel by the yellow led on.

WARNING

CAUTION: When the load is being supplied from the bypass line through the automatic bypass, it is connected
directly to the mains supply and is therefore no longer protected against main faults.

Maintenance Bypass

A second bypass circuit contained in the UPS cabinet, identified as the ‘Maintenance Bypass’ line is included to enable
the reserve supply to be made available to the load while facilitating a safe working environment for carrying out
scheduled UPS system maintenance or trouble shooting. The circuit is manually selected by the Manual Bypass Switch
(3) which can be padlocked in the OFF position.

WARNING

CAUTION: If an automatic circuit breaker device is not present in the input distribution panel, there remains a
dangerous voltage at the output terminals and also on the input terminals of the UPS module that is switched off.
Note: The load is not protected from main aberrations when operating on the maintenance bypass mode .

1.2.2 UPS Power Configuration

Figure 1-2 illustrates the Hinet UPS in what is known as the “Common Bypass” configuration. In the “Split Bypass”
configuration the static bypass line is connected by a separate power switch to a dedicated `bypass' power source that
also feeds the maintenance bypass line. Where a separate power source is not available the Reserve and Converter input
supply connections would be linked together.

With the exception of the maintenance bypass switch (3), all the isolators shown must be closed during normal UPS
operation.

1.2.3 Battery fuses switch

The battery is connected to the d.c. bus through a battery fuses switch (5) fitted inside the UPS cabinet.
